Problems with new video card re. AoC

Hi! I have a small problem & need some help if you have
the time

Recently I installed GeForce 5200, and since then I've
had problems running some games (example: Age of
Conquerors - I can enter the menu, & even play campaigns
normally, but playing a single/multiplayer battle makes
the game quit unexpectedly without any warning back to
the desktop..no error messages or anything...). On the
other hand Microsoft's Rise of Nations runs
normally...Any ideas on what can be wrong? I've tried
everything I could think of... My Dxdiag didn't show any
problems.
